Abstract The mean coordination numbers of some nickel clusters have been calculated for some proposed geometric structures for them, and their ionization potentials are obtained using an effective coordination-number model. It is shown that the mean effective-coordination number of all atoms of a cluster should be taken as a parameter to describe the d-band width of the cluster instead of mean effective coordination number of surface atoms.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
